It's a typical "scope of use" clause - you can literally take the title at it's word - "USE OF THE PRODUCTS; CONTENT IN THE PRODUCTS".

In other words, what you draw with "your" version of SketchUp, and what you do with said drawings, is your business. You just can't take SketchUp apart and modify it, sell it, bundle it... yada, yada...

It's like renting a car and pimping it out, or letting someone else drive it - you just don't do it, but you can drive it wherever the heck you want, and in most cases, use it for your business, "but" it's still "their" car.

SketchUp belongs to Trimble - works created with the software belong to you.

Thanks for the reply mitcorb...

I was messing around with it today, trying to duplicate, and instigate the undesired behavior.

It just appears to be "Hidden Geometry" becoming unhidden... Usually when I hide something, to get it out of the way of what I am working on at the moment, I'll click "Unhide All", when I'm finished. The randomly created hidden geometry, appears to just be SketchUp doing it's thing, behind the scenes, when edges, faces, and points, cross that forbidden "proximity line", where SketchUp no longer offers you a choice of precision - it just decides to do what it wants.

In future releases, they really need to crack down on the math in this program... I'm getting sick of the same root problem, that seems to know no scale, or visibility. If any two edges, points, or faces are close enough to "snap" into another form, in the free version - then there really is no point in trying to market a pay version, which is essentially the same program, and same problems.

Thanks again...

I searched the forum for something related, but to no evail...

I've been using SketchUp since Version 6, and currently Version 8, since it was released.

I encounter the strangest random bug/glitch... Random Lines will appear, and subdivide previously drawn polygons. It's only happened a handful of times in the past few months, but when it does, it has the capacity to totally wreck a complex model. Today it happened twice - the first time; 3 lines were added to a large face, no big deal, just delete the new lines. The second time however; 50+ tightly packed lines were added to a narrow face, and that entire section had to be deleted and redrawn.

In the attached image, the white area should be entirely white, no lines. The darker line near the bottom of the white area, is actually a group of several lines. When these lines showed up, I was working on a totally different part of the model, and the end points of these lines are random in nature. i.e. They look parallel, but they aren't, they're just really long. The second image, is of the bottom, of the same area - the two points that fan out int o the face, were not drawn, they just appeared, same with the void/stripe from the lower left corner.

I am aware of the small geometry issues; proximity snapping, distortion, etc... This is a large scale model - none of those issues apply.

Details;
No hidden geometry warnings pop up.
The end points of the new lines are not connected to any "deliberate" edge points.
This usually happens on any model that reaches a certain level of complexity.(not sure what level that is yet, as it never happens on the simple sketches.)
Undo has no effect - its as though they were drawn first - I have to remove all connected features, to get the new lines to stay "gone".(In most cases, simply deleting the new lines, fails, and an entire redraw is needed.)
The new lines are not always visible - sometimes they are hidden or "softened" and not selectable.(Sometimes all 4 edges of a face, can be perfectly parallel, but it will still draw a striped face.

Any suggestions or just acknowledgement of the same issue, would be great - Thanks!
